Abstract (en)

[origin: WO02090937A2] In order to remove waste water samples, particularly for photometric analysis, a quantity of filtrate is suctioned through a filtrate mesh (5) and a sample is removed therefrom and then analysed. The filtrate mesh (5) is purified in an intermittent manner in-between the removal of the samples. Said filtrate mesh (5) is electrically conductive and is impinged upon by a positive electric potential as an anode during the intermittent purifying steps in order to carry out anodic oxidation, during which a separated cathode (22, 34) is impinged upon by a negative electric potential. Said quantity of filtrate is suctioned into a filter chamber (2) through the filter mesh (5) by producing a depression. Said depression is essentially suppressed before and/or during the removal of the sample from the filter chamber (2).
